Evaluation Of Crude Protein Sources And Levels For High Growth Potential Yearling Steers Fed High Energy Diets, R. H. Pritchard
Evaluation Of Crude Protein Sources And Levels For High Growth Potential Yearling Steers Fed High Energy Diets, R. H. Pritchard
South Dakota Beef Report, 1995
Feedlot cattle are now capable of growth rates that greatly exceed our descriptions for established nutrient requirements. We must now redefined the impact of sources and levels of dietary CP on growth rate and efficiency. Pursuing this question, yearling steers (n = 360 x BW = 790 ± 10) were fed various levels and sources of supplement crude protein during a 120 day finishing period. Diets were formulated to contain 12 or 13% CP. Supplemental CP was provided in the forms of urea, soybean meal, bloodmeal, and feather meal. Actual dietary CP levels of 1 1.8% and 12.6% were lower …
Effect Of A Blood Meal/Corn Gluten Meal Supplement After Calving On Performance Of Cows Grazing Native Range, R. J. Pruitt, J. S. Heldt
Effect Of A Blood Meal/Corn Gluten Meal Supplement After Calving On Performance Of Cows Grazing Native Range, R. J. Pruitt, J. S. Heldt
South Dakota Beef Report, 1995
A spring grazing trial was conducted to determine the effect of a supplement with lower rumen degradability (sometimes referred to as escape protein or bypass protein) than soybean meal on cow and calf performance. Three supplement treatments based on corn, soybean meal and blood meallcorn gluten meal were fed to 70 Simmental-Angus crossbred cows grazing native range from early April to late May. There was no advantage to the escape protein as measured by cow weight change, reproductive performance or calf gain. Corn supplemented cows performed similar to soybean meal supplemented cows.
